前言
实不相瞒，小编作为了一个湖南人，时常被说普通话不够标准，不仅N/L不分，有时候还分不出来卷舌音，经常闹笑话，导致小编十分苦恼。有时看着电视里的主持人流利的口播，和完全标准的绕口令都羡慕不已，常常幻想着自己有一天也能说一口流利的绕口令。恰巧，小编昨日上网的时候被推送了集成了华为HMS ML Kit实时语音服务的小游戏-Tongue Twister，这款游戏究竟是如何玩转绕口令的，接下来就和小编一起一探究竟吧！
应用场景
Tongue Twister 就是一款集成了华为HMS ML Kit实时语音识别服务的绕口令小游戏，游戏中一共有5个关卡，每一个关卡就是一段绕口令，通过秘诀就是凭借强大的实时语音识别，实时语音识别服务覆盖日常生活及工作中的众多领域，并且深度优化了购物搜索、影视搜索、音乐搜索以及导航等场景中的识别能力，识别准确率高，可轻松检测闯关者的发音，如若发音清晰标准即可过关，
下面我们一起来看看这个游戏的正确打开方式吧！
这么样，是不是心动了，那就一起来试试自己定制属于你的绕口令大闯关吧！
开发步骤
1.请参见云端鉴权信息实用须知，设置您应用的鉴权信息。
2.用户调用接口创建一个语音识别器。
MLAsrRecognizer mSpeechRecognizer = MLAsrRecognizer.createAsrRecognizer(context);
3.创建语音识别结果监听器回调。
/**
* Use the callback to implement the MLAsrListener API and methods in the API.
*/
protected class SpeechRecognitionListener implements MLAsrListener {
@Override
public void onStartListening() {
// The recorder starts to receive speech.
}
@Override
public void onStartingOfSpeech() {
// The user starts to speak, that is, the speech recognizer detects that the user starts to speak.
}
@Override
public void onVoiceDataReceived(byte[] data, float energy, Bundle bundle) {
// Return the original PCM stream and audio power to the user.
}
@Override
public void onRecognizingResults(Bundle partialResults) {
// Receive the recognized text from MLAsrRecognizer.
}
@Override
public void onResults(Bundle results) {
// Text data of ASR.
}
}
@Override
public void onError(int error, String errorMessage) {
// If you don't add this, there will be no response after you cut the network
}
@Override
public void onState(int state, Bundle params) {
// Notify the app status change.
}
}
4.将新建的结果监听器回调与语音识别器绑定
mSpeechRecognizer.setAsrListener(new SpeechRecognitionListener());
5.配置识别参数，调用启动语音识别
// Set parameters and start the audio device.
Intent mSpeechRecognizerIntent = new Intent(MLAsrConstants.ACTION_HMS_ASR_SPEECH);
mSpeechRecognizerIntent
// Set the language that can be recognized to English. If this parameter is not set,
// English is recognized by default. Example: "zh-CN": Chinese;"en-US": English;"fr-FR": French;"es-ES": Spanish;"de-DE": German;"it-IT": Italian.
.putExtra(MLAsrConstants.LANGUAGE, language)
// Set to return the recognition result along with the speech. If you ignore the setting, this mode is used by default. Options are as follows:
// MLAsrConstants.FEATURE_WORDFLUX: Recognizes and returns texts through onRecognizingResults.
// MLAsrConstants.FEATURE_ALLINONE: After the recognition is complete, texts are returned through onResults.
.putExtra(MLAsrConstants.FEATURE, MLAsrConstants.FEATURE_WORDFLUX);
mSpeechRecognizer.startRecognizing(mSpeechRecognizerIntent);
6.识别完成后，释放资源
if (mSpeechRecognizer != null) {
mSpeechRecognizer.destroy();
mSpeechRecognizer = null;
}

动态权限申请
private void requestCameraPermission() {
final String[] permissions = new String[]{Manifest.permission.RECORD_AUDIO};
if (!ActivityCompat.shouldShowRequestPermissionRationale(this,

return;
}
}
总结
除了在游戏当中的应用，实时语音识别服务在使用购物类App搜索商品时，可以将语音描述的商品名称或特征识别为文字从而搜索到目标商品。同样，在使用音乐类App时，可以将语音输入的歌名或歌手识别为文字进而搜索歌曲。另外，司机在驾驶过程中不方便输入文字时，可以将输入的语音转换为文字继而搜索目的地，让行车更加安全。
